Hello, I would be grateful for any advise on wiring 1970s PAF pickups.  There are 2 x Black and 2 x White ONLY.  It appears theres a Black and White coming from each Coil?  I presume the blacks would be ground and the White Hot + I am using Braided wire, the Braided would be ground and the centre Black wire Hot +

Thanks for any advice help DH
